The Lowdown

Alright, grab your board, let’s have a look at what’s comin’ our way. It’s a bit of a mixed bag over the next couple of weeks, but there are a few windows that’ll get the stoke up.

The main event is a solid, long-period south swell that rolls in, giving us some proper groundswell. The water temp is about average for the time of year, so no need for the thickest rubber just yet.

We start off this Friday, August 28th, with a bang. Jaconé is the spot. Early morning, we’ve got a clean 4.3ft swell from the south, a 12-second period, and a nice gentle offshore breeze from the ENE. The combined energy is pumping at 556, so there’s plenty of push. This is a standout session – the waves will have shape and power, and the offshore wind will keep ‘em clean. It’s a consistent break, so you won’t be waiting around, but it can get crowded sometimes. This is your call to get out there early.

Saturday the 29th sees the swell drop off a touch to 3.9ft, swinging more east with a shorter period of 7 seconds. It’s clean in the morning with NE offshore winds, but it’s not the same quality as Friday. For the rest of the weekend and into early next week, we’re looking at smaller, weaker surf with a lot of onshore wind, so don’t expect much.

Now, hold onto your leash for Monday, August 31st. The morning brings a jump in size to 5.9ft of ENE swell, with an 8-second period and a light offshore wind from the ENE. The energy is strong at 601, and it’s looking clean. By Monday afternoon, it settles to a still-fun 4.3ft with the same clean offshore wind. This is another top pick for the week.

Tuesday and Wednesday, September 1st and 2nd, are poor. On Wednesday, a big SSW swell hits, peaking at 11.5ft with a 13-second period in the afternoon. That’s expert-only territory, and with onshore winds on top of it, the wave quality is shot. Far too big and messy for a normal paddle session.

We get a nice pulse on Thursday, September 3rd. The morning serves up a clean 6.9ft south swell with an 11-second period, cross-offshore winds from the ENE, and excellent conditions for experienced surfers. The energy is a meaty 1096.

Friday, September 4th, keeps the fun going with a clean, moderate offshore wind and 6.2ft south swell. The energy sits at 802. It’s a touch smaller than Thursday but still a solid, clean day.

After that, the surf slowly fades. Saturday the 5th and Sunday the 6th are still rideable, especially Sunday the 6th with a nice 4.6ft south swell and a long 13-second period, with light offshore winds keeping it glassy. The energy is a healthy 770.

The second week gets quiet. There’s a gap from around the 7th of September with mostly onshore winds, smaller waves, and poor conditions. There is a tiny window on Thursday, September 10th, with a clean 2.6ft south swell in the morning, and a slightly better one on Friday, September 11th. The afternoon of the 11th has an interesting pulse: a 4.9ft south swell with an 11-second period, light winds, and a solid 565 energy – it might just be the last fun session before a flat spell.

After the 12th, it really drops off, and there’s nothing worth chasing for the rest of the window.

So, to sum it up: your best bets are Friday morning, August 28th and Monday, August 31st for the best combination of size, clean conditions, and manageable crowds. The big swell on Wednesday, September 2nd is one for the experts only, and the second week has a couple of sneaky clean days but nothing compared to that first week’s punch.

Stay salty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
